Right. Look what Israel did to the USS Liberty and it was clearly in international waters and not in a river with the boundry running down the middle.
That attack was clearly an accident. Or are you suggesting otherwise?
even casual research into the incident clearly indicates a coordinated, deliberate attack on a clearly marked US navy ship by the israeli air force and torpedo boats.
back to the original post. i highly doubt anything will arise from this incident, at least i hope not. maybe the brits were probing iranian waters and the iraninas are flexing a little muscle. seems like politics as usual but likely a pretty stupid move on both sides.
